The Quechua Bionnassay 600 is made from NovaDry, a 3-layer laminate with a membrane that offers good breathability figures (that said, it only boasts a 5 metre hydrostatic head, while higher-priced jackets offer around 20 metre hydrostatic heads, so like any lower-priced jacket it may not compare as well in the long term as higher priced options). The jacket is light at just 516g (size men’s L) and its short, closer-fitting and more active style will appeal to scramblers and climbers as well as anyone wanting to move faster than some longer, heavier jackets might allow. There are two huge chest pockets, which can be accessed easily while wearing a rucksack. As these pockets are mesh-lined they will improve airflow, and save weight, but they may not be the best option for keeping rain out. There are also pit zips that extend down the sides to improve ventilation. The sleeves are quite a close fit, but they still allow excellent freedom of movement. The hood is a good close fit and moves well with the head, although the peak is perhaps not quite as good as others, however it is at least stiffened. The Quechua Bionnassay 600 is well-designed to save weight and money, but if you are out in really heavy rain then a longer design with sealed pockets may be worth the extra weight. You can get higher-specification fabric at this price, too.
